8:30 - 11:00 A.M.

Meet at the El Polin parking lot in the Presidio at the end of McArthur Ave.

(The parking lot is small and carpooling is encouraged)

Explore the Presidio's largest watershed and look for some of San Francisco's spring and summer birds- and who knows, maybe a late vernal vagrant. We'll walk along the ecology trail and visit El Polin spring and a variety of habitats including a restored serpentine grassland.
